Sounds like really bad advice to me. With the union file system you should be able to add programs. Also see the klik forum, a great system that was designed to add programs even without the union file system. Installing Knoppix is not good advice unless it contains warnings of the problems that those who try to do it often face, as Knoppix is intended as a live CD, not a hard disk installed system.
